Nonsimultaneous hierarchy: Multifractal analysis
Physical Review A, 1990We define a simple hierarchical model in two dimensions incorporating two independent and nonsimultaneous rescaling procedures in orthogonal directions. The multifractal framework and corresponding thermodynamic formalism necessary for analyzing models of this type are set up using the concept of partial dimensions, and the model is then analyzed.

Multifractal analysis of earthquakes
pure and applied geophysics, 1992Multifractal properties of the epicenter and hypocenter distribution and also of the energy distribution of earthquakes are studied for California, Japan, and Greece. The calculated D q −q curves (the generalized dimension) indicate that the earthquake process is multifractal or heterogeneous in the fractal dimension.

Box-counting multifractal analysis
Physical Review A, 1992Two box-counting algorithms for the determination of generalized fractal dimensions are described. Results of application of the algorithms to Euclidean curves, quadric islands, Koch symmetric and asymmetric triadic snowflakes, and split snowflake halls introduced by Mandelbrot [Fractal Geometry of Nature (Freeman, New York, 1983)] are described ...

Multifractals, texture, and image analysis
Proceedings 1992 IEEE Computer Society Conference on Computer Vision and Pattern Recognition, 2003Image analysis using texture and multifractal paradigms is addressed. Multifractal theory and its application to image description are discussed, and it is shown that this approach allows the discrete signal to be worked on directly. A system for texture classification that is based on a learning scheme and does not make use of any a priori model is ...

Multifractal analysis of ZnO nanoparticles
Materials Science and Engineering: C, 2020ZnO nanoparticles (NPs) have variety of applications in different fields due to its size, structure, as well as physical and chemical properties. One of its prominent characteristics is its antibacterial behavior. Nonlinear Dynamical Theory (NLD) has a vast scope in the field of material science, especially when subtle correlations are searched for to ...

Multifractal radiographic analysis of osteoporosis
Medical Physics, 1994An important complication of osteoporosis is fracture. Alteration in bone structure, as well as decreased bone mass, contribute to the tendency to fracture in osteoporosis. Current methods that measure bone mass alone show substantial overlap of the measurements of osteoporotic patients who fracture with those that do not.

Reading multifractal spectra: Aging by multifractal analysis of heart rate
EPL (Europhysics Letters), 2011The method of effective reading of multifractal properties is proposed. The method consists in the analysis of a given signal together with the analysis of an integrated signal. A practical way to separate monofractal-type signals from other signals is given. The method is applied to 24-hour ECG recordings of RR-interbeat intervals to assess the effect

Multifractal Analysis of Hyperbolic Flows
Communications in Mathematical Physics, 2000One of the main goals of this paper is to establish a version of the multifractal analysis for a class of hyperbolic flows and suspension flows over subshifts of finite type. As a consequence they show that for every Hölder continuous function non-cohomologous to a constant, the set of points without Birkhoff average has full topological entropy.

Relative multifractal analysis
Chaos, Solitons & Fractals, 2000This paper closely follows the ideas and methods of the multifractal analysis as developed in [\textit{L. Olsen}, Adv. Math. 116, No. 1, 82-196 (1995; Zbl 0841.28012)] with the purpose of introducing a formalism for the multifractal analysis of one Borel probability measure \(\mu\) with respect to another \(\nu\), both defined in the same metric space \
